Free HVAC Aptitude & Entrance Practice Test
Math, mechanical reasoning, and reading — the skills HVAC programs and apprenticeships test before they take you.
Built for HVAC apprenticeship & program applicants
Going union in the pipe trades?
This test is good practice, but I built a separate app for the UA battery — same founder, built for your trade.

HVAC apprenticeship and trade-school entrance tests measure math, reading comprehension, and mechanical aptitude — the foundation for load calcs, airflow, and the refrigeration cycle. This free practice test mirrors that format so you can see where you stand before test day.
Your trade has its own app
PipePrep AI — built for the UA pipe trades battery
If you are applying through a UA local, HVAC-R service techs sit the same aptitude battery as steamfitters and plumbers. (Going in through a non-union shop or a trade school instead? That path usually has no aptitude battery at all — you would not need either app for it.)
Straight up: I’m an IBEW journeyman electrician and a pre-apprenticeship instructor — not a UA member. What I know cold is how union selection works, and that part is the same across the building trades. The test content is not, which is why it’s a separate app.

What is the HVAC aptitude test?
HVAC programs and apprenticeships use an entrance aptitude test to screen applicants on math, reading comprehension, and mechanical reasoning. It confirms you have the foundation for the trade — measurement math, airflow and pressure concepts, and the refrigeration cycle — before training begins.
What math is on the HVAC test?
Fractions and decimals, percentages, ratios, basic algebra, and applied problems like BTU and tonnage conversions (12,000 BTU/hr = 1 ton) and CFM airflow. A calculator usually isn’t allowed, so mental math speed matters.
How should you prepare?
Drill fractions and measurement math first, then practice the trade conversions (BTU, tonnage, CFM). Use this free practice test to find your weakest section and focus your study there.
Frequently Asked Questions
Is this an official HVAC test?
This is a free practice test that mirrors the format HVAC programs and apprenticeships use — math, reading comprehension, and mechanical reasoning. Exact questions vary by program, but the sections and difficulty are representative.
What is on an HVAC aptitude test?
Math (fractions, percentages, BTU/tonnage and CFM conversions), reading comprehension, and mechanical reasoning (airflow, pressure, pulleys, heat transfer).
